If you have time, walk toward the sun, west along the beach at Long Key State Park. Keep going. Now go a little farther until you reach this sign (No trespassing). The water is public property, but the sand in this location is private property. It is an interesting situation. If you want to see what the white coral sand looks like without the seaweed on it, this is it! Coral sand is ground to small pieces by wave action, rubbing broken pieces of coral against other coral, but a major contributor is the parrot fish, which grinds the coral structure to find the animal inside the coral that makes the calcium shell. The coral needs sunlight because the animal's main food supply is the algae that grow around the structure. To see all of this, visit the Museum of Discovery and Science (MODS) in Fort Lauderdale, near the Riverfront area and Las Olas Blvd. Well, let's continue our drive.
